Ultralong temporal coherence in optically trapped exciton-polariton condensates
K. Orfanakis, A. F. Tzortzakakis, D. Petrosyan +2
We investigate an optically trapped exciton-polariton condensate and observe temporal coherence beyond 1~ns duration. Due to the reduction of the spatial overlap with the thermal r…
Quantum confined Rydberg excitons in CuO nanoparticles
Konstantinos Orfanakis, Sai Kiran Rajendran, Hamid Ohadi +4
The quantum confinement of Rydberg excitons is an important step towards exploiting their large nonlinearities for quantum applications. We observe Rydberg excitons in natural nano…
Synchronization crossover of polariton condensates in weakly disordered lattices
H. Ohadi, Y. del Valle-Inclan Redondo, A. J. Ramsay +5
We demonstrate that the synchronization of a lattice of solid-state condensates when inter-site tunnelling is switched on, depends strongly on the weak local disorder. This finding…
Strain-assisted optomechanical coupling of polariton condensate spin to a micromechanical resonator
O. Be'er, H. Ohadi, Y. del Valle-Inclan Redondo +5
We report spin and intensity coupling of an exciton-polariton condensate to the mechanical vibrations of a circular membrane microcavity. We optically drive the microcavity resonat…
Spin order and phase transitions in chains of polariton condensates
H. Ohadi, A. J. Ramsay, H. Sigurdsson +8
We demonstrate that multiply-coupled spinor polariton condensates can be optically tuned through a sequence of spin-ordered phases by changing the coupling strength between nearest…
Tunable magnetic alignment between trapped exciton-polariton condensates
H. Ohadi, Y. del Valle-Inclan Redondo, A. Dreismann +6
Tunable spin correlations are found to arise between two neighboring trapped exciton-polariton condensates which spin-polarize spontaneously. We observe a crossover from an antifer…
